Cognitive impairment is an impairment of one or more aspects of the cognitive process, including reduced efficiency or impaired function in memory, computation, comprehension, orientation, structural ability, executive ability, etc. The degree can range from mild cognitive impairment to dementia, which in turn affects the individual’s function and quality of life. There are various rehabilitation modalities for cognitive impairment, and the following is a summary of the rehabilitation treatment modalities to give you a brief introduction. Cognitive training with the help of simple tools is currently the norm. Simple tools commonly used in hospitals or rehabilitation institutions for cognitive training include: guessing, deletion, time sense, and sequencing for attention disorder training; extraction of information, sequencing, classification of items, general to specific reasoning, problem solving, and calculation and budget training for thinking disorder training Internal strategies, external strategies, and error-free learning methods for memory training; numeracy training, executive and problem-solving skills training, and training for dyslexia and dyscalculia, etc. Computer-assisted cognitive rehabilitation training and the application of virtual reality technology Computer-assisted cognitive rehabilitation training uses computers to assist patients with cognitive dysfunction and increase their interest in treatment. Computer-assisted cognitive training is more effective than manual cognitive training in improving executive functions and activities of daily living, and it is worth promoting the application of computer-assisted cognitive training in patients with brain injury. Non-invasive brain stimulation techniques have become a hot spot for research in recent years, and the clinical application is still in its initial stage. Traditional rehabilitation therapy has a certain effect on the improvement of cognitive dysfunction. Cognitive dysfunction belongs to the category of neurological disorders in Chinese medicine, and “dementia”, “dullness”, and “mental dullness” are similar to them. The symptoms of “dementia”, “cretinism” and “dementia” are similar. Commonly used traditional rehabilitation methods include acupuncture and moxibustion, traditional Chinese medicine, etc. Other methods such as hyperbaric oxygen therapy can improve local tissue hypoxia, improve blood circulation in the focal area, promote brain cell metabolism, improve brain function, and promote recovery from post-stroke cognitive dysfunction. Some drugs are also commonly used in clinical work to improve cognitive impairment, such as: cholinesterase inhibitors (e.g. donepezil hydrochloride, carboplatin, galantamine, etc.), non-competitive N-methyl-D-aspartate receptor antagonists (memantine, etc.) and other drugs (nicergoline, butalbital, etc.).
